An attic may be converted to a living space, to be kept conditioned so it’s warm in the winter and cool in the summer like the rest of the house. This can increase the amount of living space in the house. Consult your local code official for permission to use an unvented attic design; a sign off from a third party engineer may be required. Icynene can provide more information if you or your code official have questions.
- Insulation performance compromised by sagging and gaps, leading to energy loss
- Moisture ingress causing condensation and mould issues
Results of Using Icynene to Insulate Attic Rooms:
- Insulation stays in place against sloping roofs and unusual shapes, keeping the R-value as specified and maintaining an air seal to save energy.
- Bulk moisture is kept out by the air barrier, protecting against condensation and mould and improving indoor air quality.
Factors to Consider
Using Icynene spray foam insulation as roof insulation air seals the attic. When it’s used as a living space, you’ll need to ensure that the space has mechanical ventilation to maintain the required number of air changes. Adding a heat recovery ventilator (HRV) / ventilation with heat exchange and a humidistat/timer can help you achieve this goal while keeping your heating bills low. Speak with your HVAC engineer for more details.
